93 YJ ignition coil harness wire trace

Where do the two wires coming out of the coil harness / plug go to?
Ground? 12v? Pcm? Fuse block?

Years ago I had to fix a nick in the wire near it and just recently one wire broke and sent me hunting other demons like the CPS.
I'd like to replace both wires and run a new pair to wherever they go, but I can't tell where they go.

Help? Experience? Diagram?

2.5L ax5 manual.

Thanks

Dk/gn is 12v from asd

gr is control/driver to pcm #19

When I see the price of OEM I think aftermarket.

The two wires I have look like green with a orange tracer and a white or gray wire.

So one wire goes from 19 on PCM to the ASD and then from ASD to coil?

Second wire just a ground? Or?

Thanks for helping out!

the GN/OR goes to ASD relay

The GR (gray) goes to PCM
